Shalan Steel, located in Kuala Lumpur, Malaysia, has earned a solid reputation as a manufacturer and supplier of top-notch steel pipes designed for various industrial, structural, and engineering needs. With a strong commitment to adhering to international standards and ensuring dependable performance, Shalan Steel’s products are widely utilized throughout Southeast Asia. A standout in their lineup is the Carbon Steel DIN 1629 Pipe, a seamless circular steel pipe that excels in high-pressure and high-temperature environments. Known for its remarkable durability, precise dimensions, and versatility, this pipe is a go-to choice for engineers and project managers in sectors like oil and gas, power generation, and general mechanical applications.
The Carbon Steel DIN 1629 Pipe is crafted from unalloyed steel grades such as St 37.0, St 44.0, and St 52.0, featuring a carbon content that falls between 0.17% and 0.22%, along with manganese levels reaching up to 1.20%. These pipes are produced seamlessly, either cold or hot finished, and are supplied in a normalized state. The mechanical properties differ by grade, with tensile strength typically ranging from 340 to 520 MPa and yield strength from 235 to 355 MPa. They boast excellent formability, weldability, and pressure resistance, making them perfect for challenging environments. Manufactured to meet the stringent dimensional tolerances outlined by the DIN 1629 standard, these pipes are built to last.
